We are using a board with a Au1550 with cardbus (PCI1520) and
USB2.0. The USB controller is directly connected to PCI.
Although cardbus isn't fully tested yet, USB seems to work fine
(atleast i haven't heard of any problems), but i don't know
from the top of my head which chip they used.

Also, the Au1550 doesn't seem to have the master-behind-bridge
bug as the 1500 does (at least according to the datasheet),
so i guess cardbus should work also with "decent" cards :)
